FLESH-REDUCING mAcnInE.

Application filed October 24, 1927. Serial No. 228,369.

This invention relates to apparatus of the type employing a vibratingstrap applicable ody for the purpose of reducing excess flesh.

An object of the invention is to provide a simple, practicable machineof low cost in construction and in operation. I Another object is toprovide an oscillating arm for actuating the stra and provide meanswhereby the rate of vi ration and the length of motion of vibration areconcurrently regulated, and in this connection an object isto providemeans for concurrently increasing the length of strap motion as the rateof motion is decreased and vice versa.

Another object is to provide a'machine of this class which issubstantially fool-proof and has but a single control device manuallyadjustable to regulate both speed and stroke of stra vibration.

An important object is to provide a machine of such design andassociation ,of parts that eflicient action is assured with a minimumfactor of misadjustment of the mechanism by inexpert operatives.

A further object is to provide a reducing machine, in which a treatmentstrap is extended from a cabinet, and which is provided with adisappearing latform having the function of an anchor or a brace whichconstitutes a front door for the cabinet when not in use.

Figure2 is a plan of the mechanism, the

cabinet being in horizontal section.

Fi e 3 is a detail cross-section of the eccentric drive shaft and ofthe-shlft gear rack.

Figure 5 is a side view of a strap hltch. Figure 6 is a detail of theoscillator drive Figure 7 is a plan of a modified form of drive shaft.

The apparatus includes a substantial cabinet 2 having a front door 3hinged at 4 on Figure 4 is a side elevation of the shift its bottom edgeso as to swing down from a vertical, front closing position to aninclined position (Fig. 1). The door 3 carries aninner panel 5 hinged at6 along the top edge of the door so as to .fold outward andflat downupon the floor and, in this position, serve as a platform on which the'individual to be treated may stand. The loaded platform is designed tooperate as an anchor for the opened door 3 while this is inclined in thecabinet bracing position against the tipping tendency of'the treatmentstrap'8 which is extended in front of the cabinet andpassed around anyportion of the body to be treated to vibrations of strap action.

The strap actuating mechanism ismounted on a solid shelf or base '10 inthe upper part ofthe cabinet and includes a horizontal oscillatinglever11 centrally pivoted one pin 12 in'the head of a pillar 13 on the base10.

On the .ends of the lever are pivoted hitch plates 14' having eyes 15'to receive hitch hooks 16 of the-stra 8.

Means are here provided to oscillate the lever 11 and to change thelength of stroke and the rate of speed of oscillation, and to effectthese changes concurrently through a single hand control. Such meansincludesa collar 18, sliding on an arm of the lever 11' and havingopposite pivot pins 19 engaging in a connecting link 20 which has a wldeeccentric strap 21 mounted on'a flanged eccentric 22 which'is keyed onits shaft 23. This shaft is slidably supported in journal blocks 24 onthebase 10 and has a fixed friction gear pinionv 25 which is slidableradially across the cooperative .friction face of a'disc 26 set parallelto the shaft 23. The disc is fixed on I a counter shaft 27 .slidable inboxes 28 under disc snug against the shiftable pinion 25, whose movementtoward the disc center decreases the speedof the'shaft 23, and-viceversa. p

The shaft 27 is driven by a suitable transmission nieans, as a belt 30from a motor M. The driving link 20 reaches forward through the loop ofthe belt 30.

The link 20 is so positioned on the shaft 23 as to move toward the pivot12 of the arm 11 as the pinion 25 moves toward the center of the disc26. This is done so that as speed of oscillation is reduced the lengthof stroke (of oscillator 11) is increased and on reverse shift of shaft.23 speed is increased concurrently with a reduction of stroke length.

the thrust of a spring 29which-presses the v This makes the apparatusfool proof since over-length stroke cannot be combined with ion 25 andhas on its'bottom a rack 34 which constantly meshes with a pinion 35fixed on the near end of a hollowvrod 36 endingnear j the pillar 13 andslidably receiving the near end of a stem 37 having a hand wheel 38 bywhich the rod 36 may be rotated. The pinion 35 and rack 34 operatebetween confining hearings on the base 10. When the hand wheel is turnedto desired control position-it is shifted inward (with the stem) and isinterlocked by a holding pin-39; thereby maintaining all operating partsin selected position of operation. i

4 The mechanism chamber of the cabinet is closed by a set of inner wings40 hinged at 41 to open when necessary. The hand wheel is adjustable toa convenient position in front of the wings 40.

."stroke of the oscillator 11.

the eccentric 22 is fixed on the shaft and the friction pinion 25 issplined thereon and is shiftable by a yoke 42 so that speed of the shaft23 may be changed-independent of the .7 What is claimed is: 4 3

1. An excess flcsh reducing machine cabinet, having; a front doorconnected to the cabinet so as to be laid obliquely as a brace, and ananchor part connected to the door and forming a platform for theindividual being treated.

' 2. In an excess flesh reducing apparatus, a cabinet having a frontdoor hinged thereto to fold down and form an oblique brace, and aplatform connected to said door to be extended and form an anchor forthe brace, said bracing stabilizing the cabinet against the pull of thebody on an applied operating strap extended from the cabinet.
